[PATCH 2/8] staging: comedi: usbduxfast: use module_comedi_usb_driver()

H Hartley Sweeten hartleys at visionengravers.com
Wed Jun 20 19:01:14 UTC 2012


Use the module_comedi_usb_driver helper macro to initialize this
module. Rename the driver structs to follow the pattern of the
other comedi driver types and add some whitespace to improve
readability.
